== Notes and version constraints ==
* No current pricing, stock, or warranty information in the source – confirm with the supplier
* If the WiFi signal is weak, adjust the board orientation and keep the antenna unobstructed
* Flash contents are erased before every firmware download; the process takes about 1 minute
* Exact pin assignments are version-sensitive – check the latest datasheet before use
* Mac/Linux users should follow separate installation instructions than those documented for Windows 10
